9-23-2009 update: As reported in the thread below, SanDisk issued a release today stating that it will not be providing a pitch fix for its players.

Per SanDisk today at the SanDisk Sansa Clip+ forum, in a pitch bug thread:

All,

The SanDisk Firmware developers are aware of this issue and a fix is in the works for the Sansa Fuze and the Sansa Clip+. At this time due to development targeted on the Clip+, firmware for the original Clip is not currently under development. This may change in the future as time permits. . . .
